UBL-CR-491: Leave the pricing exchange rate out of the invoice

What it means

This rule checks that the invoice or credit note has no cac:PricingExchangeRate directly under its root element. This UBL element gives the rate for converting prices from one currency into the invoice currency. Unit prices, line amounts and invoice totals use the invoice currency (BT-5), with a separate provision for the VAT total in the VAT accounting currency (BT-111).

Why it matters

A PricingExchangeRate is not a substitute for stating unit prices and line amounts in the invoice currency.

How to fix it

Delete cac:PricingExchangeRate directly under Invoice or CreditNote. If your prices are agreed in another currency, convert them in your invoicing software and issue the invoice in one currency, or set the invoice currency to the one your prices are in. If you build the XML yourself, check that invoice amounts use the currency in cbc:DocumentCurrencyCode, except for the VAT total explicitly given in the VAT accounting currency (BT-111). Recheck the corrected file.
